Features
It probably to be for a horn, has been used it with a 3way speaker
・ requested elsound directly to lower the gain by -12db
・ L sound's balanced mono amplifier
Btl monaural amplifier with fully balanced input inverting amplifier circuit (for horn drive)
Following the previously announced "Epm-30inv", this is a small output machine for driving a horn.
Maintains perfectly balanced transmission up to the speaker.
Until now, balanced transmission has been treated as a high-end level only because it is not easily affected by noise, but it is effective when pulling wires for tens of meters like recording studios and theaters but it is mostly used at home it's meaningless.
However, for example, mc and mm cartridges are originally balance elements and do not have hot and ground directions
It is strange to convert this to unbalanced, transmit it, and amplify it unbalanced, and if the original is balanced, it is better to transmit it to the speaker as it is.
The same applies to cd players and dacs with balanced output.
Btl circuit that is not easily affected by the back electromotive force of the speaker.
The inverting amplifier circuit has excellent sound reproducibility and is said to be the ultimate, but it was almost buried in the dark because the input impedance could not be raised, but in the vacuum tube era, 1/10 of the input of the old circuit in the semiconductor circuit impedance is sufficient
And there is no problem as long as you do not connect a preamplifier with a very high output impedance
We have responded in a custom-made manner so far, but this time we will officially publish it in the catalog.
Sound separation and fusion in front of you. The separation resolution in the low range is excellent. Also, as a matter of course, the localization is stable by using a monaural configuration.
The epmw-30 is an unbalanced (rca) compatible btl amplifier that consists of a combination of inverting and non-inverting circuits, but this time the amplifier is a product that specializes in balanced input (rca input is also possible with an adapter). There is.
Due to the
Specifications of the diode option for sic schottky barrier rectification , the maximum output is about 80%.
It is currently impossible to change the output due to the voltage, but please contact us in case of any inconvenience.
